# OpenPresentation Free, MIT-licensed presentation JSON, local libraries, CLI, and portable agent skills. No model provider, account, API key, or paid service is required by the local tools. Font/dependency licenses are separate. Source package version: 0.7.0. Snapshot SHA-256: 0012d904a515f322dee7ec9a419e2eaa4a05beab690cc191354d4d7b68d27e7e. This identifies source content, not a verified npm release. ## Start - [Agent quickstart](https://www.openpresentation.org/agents) - [Human-readable docs](https://www.openpresentation.org/docs) - [Skill and raw-file manifest](https://www.openpresentation.org/skills.json) - [Complete Markdown guide bundle](https://www.openpresentation.org/llms-full.txt) - [Canonical schema](https://www.openpresentation.org/schema/opf/v1) - [Source repository](https://github.com/OpenPresentation/opf) ## Skills - [opf-author](https://www.openpresentation.org/agent-docs/skills/opf-author/SKILL.md): Create or revise OPF presentation documents from a brief, notes, or source material. Use for slide content and narrative authoring in Open Presentation Format, rather than generic PPTX manipulation. - [opf-edit](https://www.openpresentation.org/agent-docs/skills/opf-edit/SKILL.md): Modify existing OPF documents or integrate OPF canvas, schema-inspector, transfer, and gallery APIs. Use for precise edits, undoable imports, live preview controls, and preserving document structure. - [opf-export](https://www.openpresentation.org/agent-docs/skills/opf-export/SKILL.md): Render OPF in a browser or export OPF to SVG, PNG, PDF, and PPTX; inspect PPTX imports. Use for font/asset fidelity, reproducible output, and distinguishing schema validity from visual/export parity. - [opf-inspect](https://www.openpresentation.org/agent-docs/skills/opf-inspect/SKILL.md): Inspect OPF schema fields and catalog records or diagnose invalid OPF documents. Use for exact allowed options, schema-versus-reference warnings, and local format validation rather than visual-fidelity certification. - [opf-layout](https://www.openpresentation.org/agent-docs/skills/opf-layout/SKILL.md): Arrange OPF blocks, nested groups, promoted regions, and pagination. Use for slide overflow, layout constraints, composition geometry, or preserving content while splitting slides. - [opf-presets](https://www.openpresentation.org/agent-docs/skills/opf-presets/SKILL.md): Discover and apply OPF themes, layouts, color and font schemes, narrative and audience presets, or gallery examples. Use for catalog IDs, inline overrides, design inheritance, and font choices. ## Guides - [docs/agent-skills.md](https://www.openpresentation.org/agent-docs/docs/agent-skills.md) - [docs/BACKLOG.md](https://www.openpresentation.org/agent-docs/docs/BACKLOG.md) -
